Disadvantages

• Limited Voltage Rating: The voltage rating of 60V may not be suitable for high-voltage applications.
• Temperature Sensitivity: Its performance may be affected by extreme temperature conditions.

Working Principles

MINISMDC035-2 operates based on the positive temperature coefficient effect of the polymeric material. Under normal operating conditions, the device has low resistance. When an overcurrent event occurs, the device self-heats, causing its resistance to increase rapidly, thereby limiting the current flow and protecting the circuit. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

MINISMDC035-2 finds extensive use in various electronic applications, including: - Consumer Electronics: Such as smartphones, tablets, and portable electronic devices. - Automotive Electronics: For overcurrent protection in vehicle electronics systems. - Industrial Control Systems: Providing protection for control circuitry in industrial equipment.
